Well guys I am thinking about buying the streetporting template from Racing Beat to port my housings. How hard is it to streetport if you have the right tools...dremel and drill bits. I was thinking about getting some complete junk housings to practice on...but I will certainly take my time and get it down before I jump on to my rotor housings. Someone let me know Please. Thanks
Mike

 

it isn't all that hard if you take some time to practice. the biggest problem i see is people not beveling and polishing their closing edges, this causes HUGE problems.

 

Quite a pain in the *** with just a dremel, though practice makes perfect, it's nice to have wrecked housings to figure out just how much material you have to play with.

 

if you use a template then there is no guesswork. best not to take too much material off anyways or you can run into the coolant jackets fast. i used RB templates but enlarged them somewhat but i had some spare irons also.

 

The key to porting irons, even with a template, is to use your pinky or other fingers and feel the thickness of the upper port wall from behind and inside...I use my index and thumb. You know what it feels like touching them together, so you can get a close judgement of how much material is left when you use them to feel of the thickness of the port wall. IF you feel a lot of heat being conducted through a certain spot in the wall then STOP, and if it feels like it's thinner than 1/8" then STOP.

Remember to tape off (thick duct tape) all around the port in case your bit skips off on you, which is EASY to do, even for someone experienced.

You'll need several bits to do the job well, I mostly use stones (1/4" dia and 3/8" conical) and diegrinder for the irons and high speed metal cutters (about 3 per housing) with dremel for the rotorhousings.

 

Where can i get these stones and what is the best tool to use for the streetporting?

 

IF you cant read and fully understand what's been written so far, you shouldnt try this on your own. IMO.

 

I understand....just thought someone had prices on these stones. I have a dremel and I will get a diegrinder.

 

RotaryResurrection has provided a good summary.

Remember to always keep the bit moving. Never stay at a constant - especially a die grinder, and have hands as study as a surgeons.

A first attempt on porting my Housing. Turned out great!

 

That port looks great....nice and smooth...What kind of streetport does the template from Racing Beat provide. Is it a Aggressive streetport or a Mild Port or what and how much can you extend the ports before you are in danger of going to far. Those templates are cheap and I can save money doing my own porting.

 

If you have to ask where to get the tools, I don't recommend doing your own porting. It's very easy to turn a cheap do it yourself porting job into an expensive one by killing a housing or two.

That said, if you stick with a template, it's hard to get in trouble. But if you do things wrong, you can end up trashing a housing or an entire enigne (imagine how annoying it would be to pull an engine apart because your ports ate your side seals).

I recommend the RB street intake and exhaust templates if this is your first job.

 

I will definitely stick with those templates and that way everything will be alright.

 

good, but make sure you put a bevel or radius on the port edges or you'll get some funky apex seal wear.

 

A lil common sense goes a long way eh? Good tips, i like this thread.

 

duh... i said that a year ago.
